Harvest estimates from WDFW's hunter reports, published per GAME MANAGEMENT UNIT as HTML tables — the only state we carry that publishes harvest as structured markup rather than as a PDF whose layout has to be recovered from whitespace. Success rates are WDFW's own and are carried verbatim. METHOD IS THE VARIANT. Archery, Modern Firearm and Muzzleloader are separate seasons with separate tags in Washington, so a hunter appears in exactly one and the 'all' row is their sum. "Multiple Weapons" is its own tag type rather than a total, and is carried as its own variant. ⚠️ TWO TABLE SHAPES. Deer and elk put the GMU in the table's caption with one row per method beneath; black bear puts the GMU in the row's first cell with no method column. WDFW also upper-cases unit names in the deer and elk reports ("101 - SHERMAN") and title-cases them in the bear reports ("501 - Lincoln") — an uppercase-only pattern reads deer and elk perfectly and silently skips every bear table. General-season reports only. WDFW's special-permit tables carry harvest by point class but no hunter count and no success rate, so they cannot be turned into a rate and are not ingested; the general-season tables cover the same units. Deer and elk carry eight seasons and black bear thirteen — the older deer and elk reports use a layout this reader does not handle and are omitted whole rather than in part.
